本发明实施例提出了一种实现处理器切换的方法、 计算机和切换装置, 能够在计算机不下电的情况下实现对主处理器的切换,避免了更换主处理器 时对计算机业务造成的影响。
如图 1 ( a ) 所示为计算机的一个示例, 该计算机包括闪存 10、 平台控 制器(PCH ) 11和多个 CPU。 所述多个 CPU包括主 CPU和从 CPU, 图 1 ( a ) 中以 1个主 CPU和 3个从 CPU示出, 例如主 CPU12A, 从 CPU12B、 12C和 12D, 所述主 CPU12 A通过直接媒体接口 ( Direct Media Interface , DMI )与所述 PCH 11相连, 所述从 CPU12B、 12C和 12D通过 QPI链路与 所述主 CPU12A相连, 所述从 CPU12B、 12C和 12D通过所述主 CPU12A 的中转实现与所述 PCH 11的交互 /通信。所述 PCH 11还与所述闪存 10相连, 所述闪存 10 主要用于保存所述计算机的基本输入输出系统 (Basic Input Output System, BIOS )程序, 所述闪存 10还可以是其他保存有 BIOS程序 的存储介质, 例如 RAM/ROM。 此外, 所述计算机还可以包括硬盘等存储介 质, 用于保存所述计算机的文档和操作系统程序等数据, 所述计算机还可以 包括 I/O设备, 例如鼠标、 键盘和 PCI设备等, 所述 PCH11可以与所述硬 盘和 I/O设备相连。
由于所述计算机进行业务处理过程中, 所述主 CPU12A和所述从
CPU12B、 12C和 12D均需要与所述 PCH 11进行交互, 而所述从 CPU12B、 12C 和 12D与所述 PCH 11进行交互需要通过所述主 CPU12A的中转, 因此现有技 术在需要更换主 CPU12A时, 只能先对所述计算机整体下电之后再更换主 CPU, 不能在所述计算机不下电时直接插拔所述主 CPU12A, 否则将导致所 述主 CPU和所述从 CPU与 PCH交互的中断, 进一步引起计算机故障或瘫痪。
为了解决这个问题,本发明实施例提出了一种计算机,如图 1 ( b )所示, 与图 1 ( a )所示的计算机相比, 所述计算机还包括切换装置, 所述切换装置 设置于所述 PCH11与所述主 CPU12A之间, 所述切换装置 13的一端连接到所 述 PCH11 , 另一端与所述多个 CPU之间设置多条连接通道, 在所述计算机启 动时, 所述切换装置 13用于打开自身与所述主 CPU之间的连接通道, 关闭自 身与所述从 CPU之间的连接通道, 使得所述主 CPU和所述从 CPU能够与所述 PCH 11通信, 保证所述计算机业务的正常处理。 在所述计算机运行过程中, 所述切换装置 13用于确定所述主处理器是否需要更换, 在确定所述主 CPU需 要更换时, 选择至少一个从 CPU, 打开自身与所述选择的从 CPU之间的连接 通道, 例如打开自身与 12B或 12C或 12D之间的连接通道, 从而所述切换装置 13可以关闭自身与所述主 CPU之间的连接通道, 以断开所述主 CPU与所述 PCH11之间的连接, 解决了现有技术中由于主 CPU与 PCH相连而无法在计算 机不下电的情况下插拔主 CPU的问题, 实现了在计算机不下电的情况下更换 主 CPU, 避免了更换主 CPU时对计算机业务造成的影响。
具体地, 在所述计算机运行过程中, 所述切换装置 13可以对所述主 CPU 的运行状态进行监测, 并根据所述主 CPU的运行状态, 确定所述主 CPU是否 需要更换, 例如, 当所述主 CPU发生故障或工作异常时, 所述切换装置 13可 以监测到所述主 CPU处于故障状态, 确定所述主 CPU需要更换, 执行选择至 少一个从 CPU, 打开自身与所述选择的从 CPU之间的连接通道的操作, 此时 所述选择的从 CPU能够通过所述切换装置 13与所述 PCH11进行交互 /通信,从 而所述切换装置 13可以进一步关闭自身与所述主 CPU之间的连接通道, 以断
开所述主 CPU与所述 pcmi的连接。 所述切换装置 13还可以进一步指示所述 主 CPU的电源控制模块对所述主 CPU进行下电操作, 以便用户在计算机不下 电的情况下更换故障的主 CPU。 此外, 所述主 CPU的运行状态还可以由所述 计算机的主板控制单元( Base Mainboard Controller, BMC )进行监测, 所述 切换装置 13还能够根据所述主板控制单元监测到的所述主 CPU的运行状态, 确定所述主 CPU是否需要更换。
在实际应用过程中,所述切换装置 13与所述多个 CPU之间的连接通道往 往会受到外界环境的影响, 为了保证可靠性, 避免所述计算机出现不必要的 故障, 所述切换装置 13在关闭自身与所述主 CPU之间的连接通道之间, 可以 对自身与所述选择的从 CPU之间打开的连接通道进行釆样, 在确保自身与所 述选择的从 CPU之间打开的连接通道能够正常工作的情况下, 再关闭自身与 所述主 CPU之间连接通道。 否则, 所述装置可以进行故障告警, 以便用户即 使知晓故障进行处理, 或者还可以打开自身与另一个从 CPU之间的连接通 道, 以确保所述主 CPU能够顺利更换。
在上述描述中, 所述切换装置 13通过将 PCH11与主 CPU之间连接切换成
PCH11与从 CPU之间的连接, 实现了故障主 CPU的在线移除。 然而, 为了保 证移除所述主 CPU之后, 所述计算机仍然能够正常响应所述主 CPU的中断, 或者能够继续执行所述主 CPU移除时正在处理的业务, 所述切换装置 13还可 以在打开自身与所述选择的从 CPU之间的连接通道之前, 触发中断迁移指令 和 /或进程迁移指令,以使得所述计算机的操作系统或者基本输入输出系统能 够根据所述中断迁移指令, 将所述主 CPU的中断迁移到所述从 CPU的寄存 器, 能够根据所述进程迁移指令, 将所述主 CPU的进程迁移到所述从 CPU的 寄存器, 保证在更换所述主 CPU后, 所述计算机的各项业务正常进行。
